SN74LV161APW TI Counter IC | 16-TSSOP | 4-Bit Binary, Asynchronous Reset

Product Overview

The SN74LV161APW from Texas Instruments is a 4-bit binary synchronous counter with asynchronous reset, designed for low-voltage (2V to 5.5V) operation. Housed in a compact 16-TSSOP package, it features a fully synchronous counting operation and a ripple-carry output for easy cascading. This device is ideal for applications requiring high-speed counting, frequency division, or timing control in industrial, automotive, and communication systems.
